feat(install): prefer Homebrew on macOS, fix README brew command

install.sh now tries `brew install --cask runware/tap/runware` first on
macOS, falling back to the binary download only when Homebrew is not
found. Update README to use the correct one-liner (adds --cask, removes
the separate brew tap step).
